"For students of Reformed theology, Juan de Valdés and the Italian Reformation gives wonderful background to theologians such as Peter Martyr Vermigli and Bernardio Ochino, but it also provides great insight into the alumbrados or spirituali and the various forms of Erasmian reform and evangelism." – Jason Zuidema, Calvin Theological Journal, 2016"The principle merits of this book are (1) its updated perspectives on the writing and basic tenets of Juan de Valdés and his followers, (2) its detailed attention to the activity and ideology in heretical circles that rippled out from Valdés' productive and influential last years (1535-41) in Naples, and (3) its admirably organized overview of the scope and historiography of reforming efforts on the Italian peninsula. With this volume, the important scholarship of Massimo Firpo is now available in English to a new generation of Reformation scholars." - Jay Atkinson, Starr King School for the Ministry
